The One Symptom GI Docs Are Begging You to Never, Ever Ignore

When it comes to concerning gastrointestinal (GI) symptoms, the list is far from short. Prepare yourself for this gross list: rectal bleeding, bloody stool, vomiting, a change in bowel habits and more.

When those arise, you probably go straight to the doctor's office (we hope!), hit up a pharmacy for some medicine or—most relatably—ask "Dr. Google" for insights.

There's another symptom that a GI doc implores people to not ignore. While it's not always that big of a deal, it can be life-threatening, at the very worst end of the spectrum.

The Symptom to Never, Ever Ignore, According to Gastroenterologists

The symptom actually seems fairly benign: Abdominal pain.

"Abdominal pain has many causes; some of them can be very serious and even life-threatening and might require urgent or emergent treatment," says Dr. Qin Rao, MD, a gastroenterologist at Manhattan Gastroenterology.

If you go to the doctor for this pain, you're in good company, unfortunately: Between five percent and 10% of people who go to the emergency room (ER) do so for abdominal pain—which means it's one of the most common reasons for an ER visit.

Causes of Abdominal Pain That Are Especially Serious

Ahead, Dr. Rao shares a non-exhaustive list of potential causes of abdominal pain. The conditions' other symptoms—that is, besides general abdominal pain—are bulleted under each.

Note that many of these medical issues are similar in symptoms. This emphasizes the importance of paying attention to your body and getting a diagnosis from a medical provider.

When to See a Doctor About Abdominal Pain

Abdominal pain accompanied by fever, chills, weight loss, dizziness or chest pain are common reasons for seeing a doctor immediately, according to Dr. Rao. He also urges seeing a healthcare professional if your pain is getting worse in intensity or doesn't go away.

The Dangers of Ignoring Abdominal Pain

Ignoring abdominal pain can be so easy, and yet, it may not always be in your best interest.

"The danger of ignoring abdominal pain is that if it is due to a serious cause, it can lead to complications such as perforation, infection or bleeding, progressing to a process called shock that can be life-threatening," Dr. Rao says.

Is stomach pain always this serious? No. But generally speaking, it's better to be safe than sorry—especially when your health and life are on the line.
